Convex blades are great for a number of different applications. They’re often used in woodworking, carving, and other tasks that require a sharp edge. While they can be tricky to sharpen, it’s definitely possible with the right tools and techniques.
In this article, we’ll show you how to sharpen a convex blade so you can keep it performing at its best.
- First, find a sharpening stone that is appropriate for the level of bluntness of your knife
- If your knife is only slightly dull, you will need a finer-grained stone, while a more dull knife will require a coarser-grained stone
- Wet the sharpening stone with water and place your convex blade on the stone at a 20-degree angle
- Use gentle back and forth strokes to sharpen the blade until it is razor sharp
- Finally, rinse off the blade with water and dry it before storing it away safely

How to Sharpen a Convex Edge on a Stone
Convex edges are found on many different types of knives, from hunting and fillet knives to pocket knives. A convex edge is created by curving the blade so that it tapers to a point. This type of edge is very sharp and can be used for slicing and skinning.
However, it can be difficult to sharpen a convex edge on a stone. Here are some tips on how to do it: 1. Start with a coarse-grit stone.
If your knife is very dull, you may need to start with a coarse-grit stone in order to remove enough metal quickly. However, if your knife is only slightly dull, you can skip this step and start with a medium- or fine-grit stone. 2. Use even strokes when sharpening.
When sharpening any type of edge on a stone, it’s important to use even strokes. This will ensure that both sides of the blade are being equally ground down and that the edge remains symmetrical. With a convex edge, it’s especially important to use consistent pressure and strokes so that the curve of the blade isn’t altered during sharpening.
3 . Work slowly and carefully . It’s better to take your time when sharpening a convex edge than to try to hurry through the process .
Rushing could result in an uneven or damaged blade . So , work slowly and carefully , using long , consistent strokes , until you’ve achieved the desired level of sharpness .
Sharpening Convex Edge Sandpaper
There are a few things to know when sharpening a convex edge with sandpaper. First, use a piece of 220-grit or higher sandpaper. Wet the paper and then hold it against the blade at a 30-degree angle.
Use long strokes along the entire length of the blade. Be sure to keep the paper flat against the blade; do not let it curl up or you’ll end up with an uneven edge. After every few strokes, check your progress by running your finger lightly along the edge of the blade.
When you’ve achieved a nice, sharp edge, rinse off the blade and dry it thoroughly before using it again.
Convex Blade Knife
A convex blade knife is a type of knife with a blade that has a curved outer edge and a concave inner edge. The word “convex” means “curved”, so this type of knife is also sometimes called a “curved blade knife”.
The convex blade shape is different from the traditional straight-edged or symmetrical knives that most people are familiar with.
Some people find that the curve of the convex blade provides them with more control over the knife when they are using it. In addition, the curved shape of the blade can make it easier to slice through certain materials, such as food or rope. There are many different types of convexblade knives available on the market, including both fixed-blade and folding knives.
Some popular brands that offer convex blade knives include Spyderco, Benchmade, and Kershaw. Whether you are looking for a new EDC (every day carry) knife or a rugged survival knife, there is sure to be a convex blade model that will suit your needs.
Convex Knife Edge Pros And Cons
A convex knife is a great option for many people who want a versatile and durable blade. However, there are some potential drawbacks that you should be aware of before purchasing one.
The main advantage of a convex knife is that the blade is much less likely to chip or break than a traditional straight-edged blade.
This makes them ideal for use in tough situations where you may need to put extra pressure on the blade. Additionally, the curved edge of the blade can be used to create different slicing motions which can come in handy when cutting through tough materials. However, there are a few potential drawbacks to consider as well.
First, because the blade is curved, it can be more difficult to sharpen than a straight-edged knife. Additionally, the curve of the blade can make it more difficult to control when slicing through softer materials like bread or vegetables. Finally, convex knives are typically more expensive than their straight-edged counterparts.
How Do You Sharpen a Convex Blade on Stone?
There are a few different ways that you can sharpen a convex blade on stone. One way is to use a honing rod or diamond rod. You can also use a flat sharpening stone, but you will need to be careful not to create any hollows in the blade.
If you are using a honing rod, you will want to start by finding the angle that you need to hold the blade at. This will be different for each type of knife, so it is important to consult your owner’s manual or another source for guidance. Once you have found the correct angle, hold the knife at that angle and run the blade along the rod from heel to tip.
Be sure to maintain even pressure as you move along the length of the blade. If you are using a flat sharpening stone, start by wetting it with water or oil. Then, find the correct angle for your knife and hold it at that angle as you move the blade across the stone from heel to tip.
As with the honing rod, be sure to apply evenly pressure throughout this process. Remember – if you press too hard, you risk creating hollows in your blade!
How Do You Sharpen a Convex Plane Blade?
Assuming you are referring to a hand plane, the following steps will help you sharpen a convex blade:
1.Start with a bevel-down plane and remove the cap iron. With a fine stone, such as an 8000-grit waterstone, establish a microbevel—a very shallow angle—on the bevel side of the blade.
Work slowly and carefully so you don’t overheat the steel and damage the temper. A few strokes should do it. Polish this microbevel with successively finer abrasives until it feels smooth when you run your finger along it from end to end; I like to finish on 12000-grit paper.
2. Next, without changing the blade’s orientation in the plane body, turn the plane over and work on the back of the blade (the flat). Again using a fine stone, hone away any nicks or burrs until the surface is glassy smooth all over. You don’t need to create a microbevel on this side; just get rid of any imperfections.
Finish up by stropping with leather charged with honing compound.
How Do You Sharpen a Concave Blade?
There are a few different ways that you can sharpen a concave blade. One way is to use a honing rod. To do this, you will need to find the center of the blade and then start moving the blade up and down the rod, keeping the edge of the blade in contact with the rod at all times.
Another way to sharpen a concave blade is to use a sharpening stone. To do this, you will need to find the center of the blade and then start moving the blade back and forth across the stone, keeping the edge of the blade in contact with the stone at all times.
What is Convex Sharpening?
Convex sharpening is a type of knife sharpening that involves using a convex-shaped abrasive to create a concave bevel on the blade. This method is often used on knives with thicker blades, as it can provide a more durable edge. It is also said to be easier to control than other methods of sharpening.
In order to sharpen a convex blade, one must use a honing rod or stone at the correct angle. The angle that you use will be determined by the shape of your blade. For most blades, the ideal angle is between 20 and 30 degrees.
To find the correct angle, hold the honing rod or stone against the side of the blade and raise or lower it until it forms a 20-30 degree angle with the edge of the blade. Once you have found the correct angle, hold the honing rod or stone in place and sharpen your blade using long, even strokes. Remember to keep the strokes consistent and always move them in towards the center of your blade.
After a few strokes, you should begin to see a burr forming on your blade. Once you have created a burr, flip your blade over and repeat the process on the other side. When both sides have been sharpened, remove any remaining burrs with a leather strop or piece of cardboard.
